Use PropSchemas inside of custom PropSchema functions

[earlAchromatic]

I am trying to serialize a Set (using custom propSchema like in #157), but would like the result to use a reference inside the custom PropSchema to point to objects in the Set.

This doesn't work though:

import {identifier, reference, createModelSchema} from 'serializr'
// transmitters is a Set
// Transmitter is the class of each Set item

createModelSchema(Receiver, {
  id: identifier(),
// Want this to be a list of refs
  transmitters: custom((model) => {
    const array = Array.from(model)
    return array.map(() => {
      return reference(Transmitter)
    })
  }, deserializer)
})

Is there a way to do this?

You can't use reference in that manner as it returns a PropSchema, not an actual object.

You should be able to achieve what you are trying with the following. The docs could be improved though.

createModelSchema(Receiver, {
  id: identifier(),
// Want this to be a list of refs
  transmitters: custom((model) => {
    const array = Array.from(model)
    return array.map(x => x.id /* or whatever is the id prop for transmitters */)
  }, 
 (identifierValue, done, context) => context.rootContext.await(Transmitter, identifierValue, done);)
})
